12U Adjustable Wall Rack

The StarTech RK12WALLOA is a 12U open-frame wall rack built from steel with a black finish. It suits installers mounting network switches, patch panels or shallow servers where floor space is limited. The ladder-type L-shape frame accepts equipment up to 39.00 lbs. Supplied flat-packed, it includes two vertical rails, front and rear horizontal brackets, 48 M6 cage nuts with screws and washers, plus assembly hardware.

Pre-Installation Checks

Verify the wall can support the combined 35.40 lb rack weight plus mounted gear. Confirm stud centres measure 12 in. or 16 in. to match the pre-drilled mounting holes. Ensure the adjustable depth range of 12 in. to 20 in. accommodates your deepest device. Square mounting holes require the included M6 cage nuts; no other fastener type fits. No cable-management features or fans are provided, so plan routing and airflow separately.

Thermals and Power

The open-frame design allows unrestricted natural convection around all 12U of equipment. With no integrated fans the rack adds zero acoustic noise and draws no power. Heat dissipation depends entirely on the installed devices and room ambient conditions. The steel frame acts as a passive thermal mass but does not replace active cooling for high-density loads.

Questions about this item

What comes in the box and is anything else needed to mount it?

The flat-pack includes two vertical rails, two front and two rear horizontal brackets, 48 M6 cage nuts, 48 M6 screws, 48 plastic washers, 16 assembly screws, 24 flat washers, 24 bolts and an instruction manual. You must supply the lag bolts or anchors that suit your wall type.

How do I choose the right depth setting for my equipment?

The frame adjusts from 12 to 20 inches deep in 2-inch increments; set it to the deepest position that still clears your wall and leaves enough rear clearance for cables and airflow.

What does the 39.00 lbs weight capacity mean once the rack is on the wall?

It is the maximum combined weight of all mounted devices the rack can hold when securely fastened to studs using the 12-inch or 16-inch mounting-hole spacing; the rack itself weighs 35.40 lbs.
